Wii Bricked Need Help!

My Wii has been soft modded for about 3-5 days then all of a sudden it just bricked for no apparent reason that I'm aware of. My Wii is updated to 4.1U and I do have preloader v0.28 installed. I am able to access the Homebrew channel as well but my main menu won't come up. I have tried many things and keep getting errors please help.
